“…Fernandes et al [6] studied the influences of infill density, extrusion temperature and raster angle on mechanical strength. Parameters optimization of FDM process for blended PLA is studied using the Taguchi method [7]. Othman et al [8] studied the influence of layer thickness on the impact strength of PLA.…”

We used finite element analyses (FEA) on Abaqus to study flexural properties of additive manufactured beams using polylactic acid (PLA) polymer. Experimental stress–strain data from flexural testing are used to define elastic–plastic properties of the material in the computation software. The flexural experiments are used to validate the FEA approach suggested. The method provides good results of deflection and stress with errors well below 10% in most of the cases. Therefore, by using the proposed approach, costs related to repeated experimental works can be avoided. In addition, the flexural rigidities of the additive manufactured beams are studied. Five different beam stiffener designs (diamond, honeycomb, square, triangular and wiggle) are studied based on beam bending theory. The force–deflection data from the flexural tests are used to determine the area moments of inertia of the beams. The honeycomb stiffener showed the highest force–deflection behaviour that led to the highest calculated area moment of inertia. However, with the lowest force–deflection behaviour, the square stiffener had the lowest calculated area moment of inertia.

“…[5][6][7] On the other hand, other authors have reported that smaller LT produces parts with higher mechanical strength. [36][37][38][39] This work showed that PLA/PBAT blend 3D parts fabricated with lower LT had higher mechanical strength. This can be explained by the deposited filaments, which are compressed against each other, causing a change in the geometry of the filaments, which become more elliptical because of the better filament adhesion.…”

Fused deposition modeling (FDM) is a rapidly growing additive manufacturing technology due to its ability to manufacture complex‐shaped parts in a simple process. FDM parts present inherent porosity due to the fabrication process. The mechanical performance of the built part depends on controlling several printing parameters of the specimen and the quantity of voids. PLA/PBAT [polylactic acid/poly(butylene adipate‐co‐terephthalate)] blend is a biodegradable polyester with bio‐based content that is used as a potential replacement for conventional petroleum‐based polymers. PBAT reduces the stiffness and improves the tear strength of PLA. There is a lack of research on PLA/PBAT 3D printed parts, especially the relationship between flexural mechanical properties and porosity of PLA/PBAT parts. The aim of this work is to investigate the effect of layer thickness (LT), deposition speed (DS), and printing direction (PD) on porosity and flexural properties of PLA/PBAT blend parts. Experimental design method is used to identify the set of parameters, which gives optimized results. Specimens fabricated with lower printing parameter values allowed obtaining parts with less porosity and consequently improved bending properties.

Natural fibers and their composites are being widely used in almost all the applications in this modern era. However, the properties of natural fibers have to be enhanced in order to compete with synthetic fibers. This review paper opens up additive manufacturing, as a novel method for developing an acoustic panel using natural fiber composites with enhanced mechanical and acoustical properties. This approach will help to replace synthetic-based acoustic absorbers with biodegradable composite panels in acoustic applications. This review also covers, poly(lactic acid) as a polymer matrix and its advantages, the available variety of natural fibers as reinforcement in terms of mechanical and acoustical properties. The natural fiber-based filaments used in additive manufacturing and acoustic panels made from the available natural fibers are also elaborated here. This review shows the importance of additive manufacturing and its application to develop novel acoustic panels made of agricultural waste.
